CUSH ION-TIRE.

Specification of Letters Patent.

Appucaticn mea June 22, 1910.

To all 'whom it may concern:

Be it known that I, PHILLrr SCHAU, a citizen of the United States, residing at Kalamazoo, Michigan, have invented certain new and useful Improvements in Cushion-Tires, of which the following is a specification.

This invention relates to improvements in` cushion tires..

It is particularly an improvement on the structure appearing in Patent No. 557,151, issued to me on March 31st, 1896.

The main objects of this invention are to provide an improved cushion tire which is very resilient and is similar to a pneumatic tire in its action, and one which is simple in structure and very durable and in which the j azts are very easily produced 4and assemle A further object is to rovide an im- ,proved construction of cushion tire which is Imade up of parts which can be readily assembled for manufacture or for repairs.

' 'Still further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The structure described constitutes one ef- Eeetive embodiment of my invention. .Other embodiments would be readily devised by hose skilled ,in the nrt.

The invention is clearly defined and pointad out in the claim.

A structure constituting an effective and )referred embodiment of the features of my,

nvention is clearly illustrated in the aecomspeci'fication, in which:

Figure 1 is a cross section of my improved -ire taken on a line correspondm to line .-1 of Fig. 2. Fig. 2 is a longitu inal sec- -ion, taken on a' line corresponding to line 2-2 of Fig. l. Fig. 3 is a top plan view of he cushion member. Fi 4 is a vertical secion, through a modifie form of cone, the one being hollow.

In the drawing, similar reference characers refer to similar parts throughout the sevral views, and the sectional views are taken ooking in the direction of the little arrows .t the ends of the section lines.

Referring to the drawing, the outer se aate casing 1- is preferably provided wit 1 a. vat tread 2 and rim-engaging flanges 3. This casingA is very similar to the casing of' a Vouter sides bel'n ing drawing, forming a part of thisl Patented Oct. 10, 1911. serial No. 568,357. i

pneumatic tiro. The casing, as here shown, isformed of rubber. VIt may be, however, formed of any suitable material.4

lVithin the casing, I arrange a cushion member comprising a band-like case 4, corresponding to the tread of the tire, having a plurality of inwardly-projecting cones 5 thereon, the cones and band being formed integiallv of rubber. IVhen there is a plurality of rows, the cones of the adjacent rows are arranged in an alternating or stan'- gered relation, as is clearly illustrated 1n Fig. 3 of the drawing.

The outer faces or sides of the cones are curved to correspond to the curvature of the sides of the outer casing. 'lVithinthe-se cones and corresponding to the rim I arrange an inner member 6, which may be 'of resilient material, although it mivht be made of wood or hard fiber. The edges of this member are conformed to the outer casing, as illustrated in the drawing, its flat to bear against the rim and its inner si e being provided with annular ribs 7 disposed between the inne'r ends of the-cones` and withlanges 8 at its edges engaging the outer sides of the inner ends of the cones. This assists in supporting the cones in an upright position and retains the parts in their proper relation.

In Fig. 4, I illustrate a hollow cone. Solid cones are, however, preferred. The cones are arranged uponthe base or tread band 4, so that their bases are in contact with each other.

By thus arranging the parts, I secure a cushion tire which is Vvery similar to a pneumatie tire in its action', is very resilient and durable. The structure is com aratively economical to produce-and can Ee readily assembled.

I have illustrated and. described mv imroved tire in detail in the form preferred E me, although I am aware that modificatlons other than those illustrated are possible. I have not, however, attempted to illustrate or describe the same herein as I believe the will be readily understood by those iski led in the art to which my invention reates.

When` this structure is considered and compared with thestructure of my former atent, it will be seen that this struct-ure can e very readily produced in continuous strips that can be readily conformed to a tire of any dimensions and be effectively vulcanized in that form. sembled in such a way that proper tension 1s put upon the cushion. The cushion cones ere retained very eectively in position by the seats lprepared for the tips of the same. This makes the structure entirely practicable for heavy work, such as an automobile tire is intended for.

Having thus described my invention,wha.t I claim es new and desire to secure by Letters Patent is A tire comprisin a separable outer casing; a cushion mem r consisting of a bend corresponding to the tread, conformed to said casing and having inwardly-projecting The parts can be ascones thereon, the outer sides of the out: cones being conformed to the said casing and an inner member corresponding to t1 rim having its edges conformed to the sai outer casing and provided with ennuh grooves disposed to seat the inner free poin of said cones.

In witness whereof, I have hereunto s Fmy hand and seal in the presence of tv witnesses.
